Windows 10: how to fix automatic scroll down problem ?

how to fix my automatic scroll down problem ?

:)

 

scrolling bad

New event. When placing cursor over a list or row of columns, even the volume bar scrolling is automatic and proceeds to one end of the series and stops. The scrolling also stops when I move the cursor away from the list but am unable to select anything in the list. Not all the possible lists are effected. Other sites have recommended mouse/kb fixes. Have tried all those but the phenomena persists. Have not had any known updates recently and don't have a restore point to try. Any other suggestions? W10Pro 1903

 

Scroll bar on main menu scrolls straight to last item

When I click on the scroll bar of the main windows menu (bottom left button) and start to scroll down, the scrolling then continues automatically to the last item on the list so that I can't access the others. It is as if gravity has taken charge! There is no problem with scroll bars in web windows or in Excel. I think the same problem was happening in Word last week but it is not today. I have tried following various recommended fixes including a clean boot, running Windows defender scan and switching off some mouse functions. I am no computer expert so it is possible I have perforemd all these actions correctly. Nothing has solved the problem. I've also tried a different mouse.
Any suggestions as to what is the cause of the problem and how I might fix it would be very much appreciated. The graphics card is fairly ancient: could this be the problem?
